</h2>
<p>
XOWA displays images by using online downloads as specified in <a href="http://xowa.org/wiki/home/page/Dev/File/Setup.html" id="xolnki_2" title="Dev/File/Setup">Dev/File/Setup</a>. However, XOWA can also be setup to use offline sources. If you have the time and storage space, you can download all the images for your wiki and run them from a hard drive. Note that the full tarball set for English Wikipedia is over 2 TB and may take 15 days to download and unzip. Even a small wiki like Simple Wikipedia requires 56 GB. Please prepare accordingly.
</p>
<h2>
<span class="mw-headline" id="Download_tarball">Download tarball</span>
</h2>
<ul>
<li>
Navigate to the Wikimedia image dump site at <a href="http://ftpmirror.your.org/pub/wikimedia/imagedumps/tarballs/fulls/" rel="nofollow" class="external free">http://ftpmirror.your.org/pub/wikimedia/imagedumps/tarballs/fulls/</a>
</li>
<li>
Select the tarball for your wiki and download it.
</li>
</ul>
<h2>
<span class="mw-headline" id="Unzip_tarball">Unzip tarball</span>
</h2>
<ul>
<li>
If you are on a Windows system, the current version of 7-Zip does not handle UTF-8 filenames (it default to CP-1252). You will need to download the latest 7-Zip alpha (I used 9.27).
</li>
</ul>
<dl>
<dd>
You can try the latest alpha here: <a href="http://sourceforge.net/projects/sevenzip/forums/forum/45797/topic/6063877" rel="nofollow" class="external free">http://sourceforge.net/projects/sevenzip/forums/forum/45797/topic/6063877</a>
</dd>
</dl>
<ul>
<li>
Unzip the tarball to the hard-drive's root.
</li>
</ul>
<dl>
<dd>
For example, on a Windows 7 system with a hard drive mounted at W, unzip to W:\. This will create a directory called <b>W:\wikipedia\common\</b>.
</dd>
</dl>
<h2>
<span class="mw-headline" id="Change_config_file">Change config file</span>
</h2>
<p>
Two changes will have to be made to the config file:
</p>
<ol>
<li>
commons source
<ol>
<li>
Search for the following: <code>.set('src_http_commons', '<a href="http://upload.wikimedia.org/wikipedia/commons/'" rel="nofollow" class="external free">http://upload.wikimedia.org/wikipedia/commons/'</a> , 'commons.wikimedia.org' ).ext_rules_('img_only').owner</code>
</li>
<li>
Replace it with the following: <code>.set('src_http_commons', 'W:\wikipedia\commons\' , 'commons.wikimedia.org' ).fsys_('wnt').tarball_('y').ext_rules_('img_only').owner</code>
</li>
</ol>
</li>
<li>
wiki source
<ol>
<li>
Search for the following: <code>.set('src_http_~{wiki_key}', '<a href="http://upload.wikimedia.org/~{wiki_type_name}/~{wiki_lang}/'" rel="nofollow" class="external free">http://upload.wikimedia.org/~{wiki_type_name}/~{wiki_lang}/'</a> , '~{wiki_key}').ext_rules_('img_only').owner</code>
</li>
<li>
Replace it with the following: <code>.set('src_http_~{wiki_key}', 'W:\~{wiki_type_name}\~{wiki_lang}\' , '~{wiki_key}').fsys_('wnt').tarball_('y').ext_rules_('img_only').owner</code>
</li>
</ol>
</li>
</ol>
<p>
Note: the .fsys_('wnt') is not needed for Linux systems. It is a "hack" for Windows systems to handle File titles that have invalid Windows NT filesystem characters (such as " or :)
</p>
<h2>
<span class="mw-headline" id="Known_limitations">Known limitations</span>
</h2>
<ul>
<li>
The tarballs do not come with thumbnails for video or pdf files. XOWA will show them as blank.
</li>
</ul>
<dl>
<dd>
These thumbnails are generated with other programs. Future versions of XOWA will try to generate them.
</dd>
</dl>
<ul>
<li>
imageMagick/inkscape will improperly identify sizes for certain svgs.
</li>
</ul>
<dl>
<dd>
For example, on en.wikipedia.org/wiki/Earth, Earth-Moon.svg is 512x320
<dl>
<dd>
imageMagick incorrectly identifies it as 1000,1000.
</dd>
<dd>
inkscape incorrectly identifies it as 1991,316. It provides an X,Y of -825,-2.9 which doesn't help.
</dd>
</dl>
</dd>
</dl>
<ul>
<li>
inkscape will improperly show artifacts in certain svgs.
</li>
</ul>
<dl>
<dd>
For example, on en.wikipedia.org/wiki/France, France_location_map-Regions_and_departements.svg will have random black lines around Paris
</dd>
</dl>

Dumping all the thumbnails in a wiki is currently being implemented. See <a href="http://xowa.org/wiki/home/page/Dev/Design/Offline_files.html" id="xolnki_3" title="Dev/Design/Offline files">Dev/Design/Offline_files</a>
